3-6 Linux Setup and Operation
Restoring Redundant Configuration Manually
This section describes procedure to change the built-in disk on which failures occurred and
re-establish the dual configuration of hard disks.
IMPORTANT:
You need to log in the system as a root user to perform this operation.
While recovery operation of RAID, the status of two disks configuring RAID
become “RESYNCING” or “RECOVERY” to build RAID for a while. Do not
stop or restart the system until that status is finished.
1. Select “RAID” – “Remove Half Disk” or “Remove Full Disks” of ftdiskadm to
separate the disk specified by the slot number from the RAID, and from the
system.
2. Remove the disk from the system and then insert a new disk.
3. Use “Repair Disk” of ftdiskadm to perform RAID recovery.
The following is an example from the separation of the built-in disk inserted to
the slot 1 of the PCI module for Group 2, to the recovery. SCSI SLOT numbers
on Remove correspond to the slot numbers of the PCI modules as:
Slot 1 to 3 of the PCI module for Group 1 : SCSI SLOT number 1 to 3
Slot 1 to 3 of the PCI module for Group 2 : SCSI SLOT number 4 to 6
